Hey there forum I have a 2004 XL and I am getting a P0442 code on my truck. It has to do with a small gas leak or something like that. WELL i need to pass my emissions next week in the county I live in. I need help if anyone else has had this code and found out what the cause was. I am hoping this is a familiar/popular code for these trucks. please any advice would be great...or if there is even a way to pass emissions without fixing the issue and trying to fix it after I pass.

 

P0442 - EVAP Control System Leak Detected (Small Leak)
The PCM monitors the complete EVAP control system for the presence of a small fuel vapor leak. System failure occurs when a fuel vapor leak from an opening as small as 1.016 mm (0.040 in) is detected by the EVAP running loss monitor test.

• After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications
• Small holes or cuts in the fuel vapor hoses/tubes
• Canister vent solenoid stays partially open on closed command
• Damaged, missing or loosely installed fuel filler cap
• Loose fuel vapor hose/tube connections to the EVAP system components
• EVAP system component seals leaking (EVAP canister purge valve, fuel tank pressure sensor, canister vent solenoid, fuel vapor control valve tube assembly or fuel vapor vent valve assembly)
